Sections should be expanded automatically if matches found in search

Steps to reproduce:

• Open content library
• Open Textures tab
• Click "Alpha" section to collapse it
• Type "Arrow" in search
• -> "Alpha" section should be automatically expanded showing the found result but it's not
• Same happens in "Environments" tab if you collapse e.g. Night section and then type "night" in search
• Auto expand seems to work correctly in Materials tab
